Is today's fine dust for real? ㅠㅠ My skin barrier feels completely destroyed...

I went out for the weekend for the first time in a while, but even though the weather was warm, my face feels itchy, probably because the dust was so bad. As soon as I got home, I deep-cleansed and put on a soothing mask, but the redness hasn't gone away. Would something like Rejuran be effective for calming the skin in a situation like this? Please share some tips on how you all manage your skin barrier during the changing seasons!
